Do you need planning permission for a wraparound extension in Magherafelt?
Here is how the rules in Northern Ireland apply to a wraparound extension in Magherafelt.
Northern Ireland's rules restrict side extensions more than rear ones, so a side infill or wraparound usually needs a planning application to the council as well as building control approval.
There is no Party Wall Act in Northern Ireland; we agree any work affecting a shared wall or boundary directly with the neighbour, in writing.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application.
What are homes in Magherafelt like to extend?
Semis and detached houses are typical of Magherafelt, and many have room for a rear extension within Northern Ireland's permitted development limits.

FAQ
Wraparound extension questions in Magherafelt
Do I need planning permission for a rear extension in Magherafelt?
Often not for a single-storey rear extension of up to 3 metres (4 metres detached) under Northern Ireland's permitted development rules, outside conservation areas.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
What roof suits a wraparound?
A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.
Do I need a party wall agreement?
Northern Ireland has no Party Wall Act; we agree any shared-wall work with your neighbour in writing.
Can you match the brick or stone on my Magherafelt house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
